Ok, he open-raises CO+2 in an un-opened pot. If he is good, he can have AA, A2, A3, A45x, and perhaps other stuff occasionally to mix things up AKJ9, KK24, 2345, JJT9, JJQQ etc. You call, so he can put you on roughly the same range minus the crappier holdings.

It’s heads up and you check. He should be betting with a fair number of hands here. QJ, Ax clubs, Kx clubs, a set, two pair. Also semi-bluff hands like AQcT8c, AQQT, and occasionally even with pure bluff hands like A288ds, since your preflop call could easily have been something like A234 that has to go away now.

When you call the flop, yes he can now narrow you to two pair or set, but wouldn’t you also call here with AKQ9ds to the K in clubs? What about QQT8ds? What about A27c8c? Why are you so sure that HE can’t be continuation betting with A27c8c ?

What happens if he has a set with the naked Ac and a club hits – then he bets and bluff you out? Or the board pairs and he holds Ax clubs and bluffs you out?

Look, the hand was played fine, and your turn read set up a nice river play. But it easily could have gone differently if his cards were different, or you got different turn/river cards.
